Answer:
B) electricity
Explanation:
The toaster works with a metallic resistance, what happens is that when electric current is left to run through a metal piece with nowhere to go it starts to heat up the metal, and that converts electric energy into heat energy, that heats up the piece of bread and toasts it. That´s why the source of the heat that made the bread hot was electricity.
